All
• Know the meanings of the words term, expression and equation
• Construct and solve simple linear equations with integer coefficients (unknown on one side only) using an appropriate method (e.g. inverse operations)
Most
• Manipulate algebraic equations
• Recognise that letter symbols play different roles in equations, formulae and functions
• Construct and solve linear equations with integer coefficients (unknown on either or both sides, without and with brackets) using appropriate methods (e.g. inverse operations, transforming both sides in same way)
• Use graphs and set up equations to solve simple problems involving direct proportion
• Substitute integers into simple formulae, including examples that lead to an equation to solve

Some

• Distinguish the different roles played by letter symbols in equations, identities, formulae and functions
• Construct and solve linear equations with integer coefficients (with and without brackets, negative signs anywhere in the equation, positive or negative solution)
• Use systematic trial and improvement methods and ICT tools to find approximate solutions to equations such as x2 + x = 20
• Use algebraic methods to solve problems involving direct proportion; relate algebraic solutions to graphs of the equations; use ICT as appropriate
